How do you determine the direction of motion?
The direction of motion is the direction the velocity vector points in. Where v1/2 is the magnitude of the velocity halfway to the top of the trajectory. So vdown=−vup – the two velocity vectors point in opposite directions not the same direction.
What is the direction of acceleration during upward motion?
What is the direction of acceleration during upward motion? What is the velocity at the highest point of its motion. The direction of acceleration is downwards.
What is the formula for velocity in equation of motion?
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
What is the acceleration of a truck traveling at 60 mph?
The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. Example 2: If a truck is travelling at 50 km/h and increases its velocity to 65 km per hour in 10 seconds, what is its acceleration?
What is the acceleration of a car in m/s?
The answer is (60 mph – 0 mph) / 8s = (26.8224 m/s – 0 m/s) / 8s = 3.3528 m/s 2 (meters per second squared) average acceleration. That would be 27,000 miles per hour squared. That would be 27,000 miles per hour squared.
How fast does a car decelerate in 5 s?
This time a car decelerates in 5 s from 35 m/s to 25 m/s. Its velocity changes by 25 – 35 = -10 m/s. Therefore its acceleration is -10 ÷ 5 = -2 m/s2
How do you find the acceleration of a moving object?
Movement can be shown in distance-time and velocity-time graphs. You can calculate the acceleration of an object from its change in velocity and the time taken. Velocity is not exactly the same as speed. Velocity has a direction as well as a speed. For example, 15 m/s is a speed, but 15 m/s North is a velocity (North is the direction).
